Patent GB-694633-A (GB)
Title: A process for the manufacture of organic compounds containing sulphonamide and/or disulphonimide groups
Filed: 1949-04-14
Abstract: Organic compounds containing sulphonamide and/or disulphonimide groups are obtained from sulphochlorides having one or more sulphochloride groups in the molecule and which have been obtained by the simultaneous action of chlorine and sulphur dioxide on saturated aliphatic or cycloaliphatic hydrocarbons which may, if desired, be substituted by halogen atoms or aryl groups by treating with aqueous ammonia containing at least 30 per cent by weight NH3 at temperatures below 0 DEG  C.  If sufficient amounts of aqueous ammonia are used and the treatment is carried out at about - 10 DEG  C. or below the products obtained contain principally sulphonamido groups in the molecule but if small amounts of ammonia are used the sulphonamido compounds formed react with unreacted sulphochloride groups to yield disulphonimides.  The formation of the latter may be suppressed by leading in gaseous ammonia during the reaction.  The products are stated to be soluble in aqueous alkalis to form salts.  In an example a mixture of synthetic hydrocarbons of average molecular weight 150 formed in the benzene synthesis from carbon monoxide and hydrogen is converted into sulphochloride by leading in chlorine and sulphur dioxide simultaneously with irradiation at 30-35 DEG  C. and the resulting sulphochloride is then dropped slowly at - 10 DEG  C. into aqueous ammonia of 45 per cent NH3 content; the reaction product is separated as a heavy viscous oil and is then warmed gently whilst a current of air is passed through to remove the smell of ammonia.  The product corresponds to the average formula C11H23SO2NH2. Similar results are obtained by using sulphochlorides derived from other aliphatic hydrocarbons or from cycloaliphatic hydrocarbons, e.g. decahydronaphthalene, both of which may be substituted by halogen or aryl groups.  The products can be used as plasticizers or as textile or emulsion auxiliary agents.  The Specification as open to inspection under Sect. 91, includes the use of aqueous ammonia with a content of more than 25 per cent NH3 and includes an additional example in which a sulphochloride derived from a saturated hydrocarbon fraction from the benzene synthesis by the Fisher-Tropsch method is sulphochlorinated as above and the product after being freed from non-saponifiable matter by vacuum steam distillation is added dropwise to concentrated ammonia at - 10 DEG  C. whilst at the same time ammonia gas is passed through the mixture, a mixture of sulphonamides corresponding to the mean formula C10H21SO2NH2 being obtained.  This subject-matter does not appear in the Specification as accepted.

Title: Presser mechanism for sewing machines
IPC: D05B29/00
Filed: 1927-04-13
Abstract: 278,270. Fairweather, W., (Singer Manufacturing Co.). April 13, 1927. Presser-bars with periodic control.-A machine having an upper four-motion feed-dog co-operating with a lower feed-dog or with a throat-plate or other means to feed the work, and a presserfoot to hold the work under control, is provided with means to allow the presser-foot to remain continuously in engagement with the work throughout the sewing, but with reduced pressure during the feeding stroke to prevent hammering action due to alternate lifting and lowering of the presser-foot and feed-foot at high speeds. Preferably, the presser-foot 29 is carried by the lower section of a two-part presser-bar between the parts 28, 45 of which, as seen in end sectional elevation, Fig. 2, a light expansion spring 46 is interposed. The heavy pressure of the usual presser-bar spring 47 is transmitted direct from the upper section 45 to the lower section 28 when the feed-foot 14 is lifted from the work for its return-stroke, but is relieved from this pressure by the straightening into alignment of the pivots 41, 42, 43, as seen in end view in Fig. 1, of toggles mechanism 39, 40. acting on the upper section 45 of the presser-bar during the feeding stroke, when the light spring 46 only acts on the presserfoot. The lower section 28 of the presser-bar is adapted to slide in the head 4 of the machine, being raised or lowered by the usual cam lever 58 or treadle-controlled lever 59. Fig. 5. The invention is described as applied to a machine wherein the work is fed between upper and lower feed-dogs 13, 14, of which the lower feed-dog 13 only engages the work in the rear of the needle 6, Fig. 7. The presser-foot 29 is extended in the rear of the needle so as to work directlv over the portion of the feed-dog 13 in the rear of the needle. The feed-dog 13 is mounted on a feedbar 15, Fig. 5, pivotally supported at 16 on a feed-rocker 17 journaled on the bed 1 of the machine. Feed lift movements are imparted by an eccentric 19 on a main-shaft 12 which is embraced by the strapped end of a slide-pin 20 working in the feed-bar 15. Feed advancing movements are imparted to the rocker by an adjustable eccentric 21 on the shaft 12, which is connected by a pitman 22 to a pin 23 on the feedrocker. The upper four-motion feed-foot 14 is carried by the feed-bar 24, which is pivotally hung from a pin 25 on a block 26 slidably mounted on the bearing bushing 27, in which, and the lower bushing 27<1>, the lower presser-bar section 28 is slidably journaled.

Title: Improvements in or relating to machines for grinding tooth flanks of gear wheels by means of profiled abrasive discs
IPC: B23F23/12
Filed: 1943-06-23
Abstract: 569,082. Grinding. AEPPLI, A. June 23, 1943, No. 10156. Convention date, June 18, 1942. [Class 60] [Also in Group XXII] A machine for grinding gears by means of discs having the shape of the tooth flanks has two discs 19 for acting on opposite flanks of a gear 6, one at least of the discs being angularly adjustable about the axis of the gear. The work 6 is mounted between a headstock and tailstock on a vertical slide 3 which is reciprocated on a pillar 2 by mechanical or hydraulic mechanism. Each disc 19 is carried by a spindle driven by an electric motor 23 and mounted in a bearing 22 on a slide 11 movable by a screw 12 on a base 8 pivotally mounted on the frame of the machine about the axis of the work and angularly adjustable by an arcuate rack 9 and pinion 10. After each traverse or reciprocation of the slide 3 the work is indexed and the depth of cut may be adjusted by rotating the work and one of the bases 8, but preferably by maintaining the work stationary and rotating both of the bases 8. The operative face of each disc 19 is trued by a diamond 15 on a pivoted holder which is given a rolling motion relatively to a slide 13 so as to generate an involute surface, the slide 13 being adjusted radially on the slide 11 by a screw. The screw 12 is rotated by hand at 7 to adjust the disc 19 to suit the diameter of the work and the screw may be coupled to the screw 12 by gearing 17, 18 such that the trueing slide 13 will be traversed through twice the distance moved by the slide 11 to compensate for the reduction in diameter of the disc due to trueing. The rolling motion of the trueing diamond may be effected automatically or by hand and one trueing device only may be mounted on the slide 3 to roll about the axis of the work, the device being rotated through 150 degrees for operating on each of the discs 19 in turn. Instead of reciprocating the slide 3, this slide may be stationary with the axis of the work vertical or horizontal and the reciprocation along the work axis given to the discs 19, and the work and grinding discs may have inclined axes for producing helical gears. Specification 569,081 is referred to.

Welding. - In an electric resistance, electric arc, oxy-acetylene or other apparatus for welding tubes and the like, the devices for compressing the seam to complete the weld are adjustable in the direction of movement of the work so as to vary the position of the zone of maximum side pressure relatively to the heating zone. These devices are also adjustable in the same direction transversely of the line of movement of the work to position the seam relatively to the heating zone. In an apparatus in which the tube seam is heated by roller electrodes as described in Specification 216,203, the compressing rolls 72 are rotatably mounted on fixed spindles 73 which are carried by slides 76, adjustable towards and from each other by a right and left hand screwed rod 82, and adjustable simultaneously in the same direction and held in position by set screws 86. The plate 85 on which the slides are mounted is secured in position on the bed 1 by screws 88 passing through elongated slots and is adjustable longitudinally on the bed and positioned by set screws. One or both of the rolls may be insulated from their spindles and from their slides by an insulating bushing and by an insulating disc 79 placed between the roll and its ball or other antifriction thrust bearing, so as to prevent shortcircuiting of the current round the welding zone. The slides 76 and plate 85 are preferably of non- magnetic material to keep down the inductance of the welding circuit.

Control of the speed and position of a member is provided in a numerical programme system having a digital-position-sensing-device, by counting for a set time the number of pulses from the position senser and comparing the result with a programmed signal representing the desired speed of movement. The speed signal is arranged to preponderate when the controlled member is remote from the required position, and is suppressed (e.g. by disconnecting the speed circuit) at a low value of positional error. As shown, data from a programme store L is processed at P to provide digital signals representing desired positions and speeds which are fed to comparators LV, GV respectively, Actual position signals from G are fed to comparator LV, and through a periodic pulse counter SG to comparator GV. The speed and position error signals are fed through digital-to-analogue converters to amplifier V to energize servomotor M. As described in detail with reference to Fig. 2 (not shown). The position senser may be a code scale scanned photoelectrically, and pulses derived from the fine track.Sp, are counted in a binary counter, and transferred to a store for comparison under the control of transfer pulses e.g. every second.

Abstract: 1,075,432. Fluidised bed reactor. PROCTOR & SCHWARTZ Inc. March 12, 1965. No. 10519/65. Heading B1F. [Also in Divisions B8 and F4] In a fluidised bed reactor for chemical or physical reactions on a material, the material passes through a treating chamber 12.2 in boxes 13.2 carried on an endless, perforated conveyor belt 10.2 and is fluidised by conditioned treatment gas passing upwardly therethrough in a series of spaced parallel streams from gas supply ducts 15.2, and at least a portion of each fluidising gas stream is abruptly returned to pass downwardly through the bed in a plurality of spaced streams to roll or tumble the material. The gases pass into gas return ducts 20.2, 21.2 intermediate the supply ducts for passage to a gas supply fan and heater or cooler (not shown). An exhaust duct outlet 29.2 is positioned in the top of the chamber for vitiated gas and a screen belt 32 driven about pulleys 33 travels above the top of the boxes to hold the material therein. The boxes 13.2 may have some or all of their peripheral sides sloping outwardly to expand the upwardly flowing gas streams so as to lose velocity and drop the material out of suspension. Stationary baffles, Fig. 4 (not shown) mounted above the conveyor may replace the boxes. The velocity of successive fluidising gas streams may diminish to compensate for increasing lightness of material, or several successive treating chambers may be utilised. Fig. 16 (not shown).
